Wont print black but colors are fine,

Have you tried setting the color to black cartridge only. You may be printing the black with a combination of colored inks. I occasionally have a similar problem. Sometimes I can get the black to work by taking a paper towel dampened with distilled water and holding it against the cartridge print head until I see black ink coming out. Replace the cartridge and try printing again. If this doesn't work try a new cartridge and run through your Printer Settings, making sure they are all set properly.

Doing reference on your issue. Double check the ink cartridge to make sure that the cartridge is correctly installed. Also be sure that the black ink cartridge used is compatible with the machine.

The next thing to do is a cartridge cleaning as the belief is that the print head is blocked. If you have done a thurough cleaning, the next thing to do is replace the black ink cartridge to be certain the ink cartridge is not faulty.

I have included print head cleaning instructions in case you have not done this cleaning process.

here is some information from the Brother support site:

If one or more of the ink colors are missing from pages printed by your machine (i.e. received faxes, copies and/or documents printed from the PC etc), nozzles in the print head may be clogged, or the ink cartridge in question may not be installed correctly. Verifying that the ink cartridges are installed correctly and/or cleaning the print head may solve the problem.

Cleaning the print head may solve the problem. When cleaning the print head, you are given the option to clean BLACK ONLY, one of the three colors (CYAN, YELLOW, or MAGENTA), or all four colors at once. For this issue we recommend cleaning only the affected color. If more than one color is missing then choose ALL.

When the machine completes cleaning the print head, press Color Start. A Print Quality Check Sheet will print.

Check the black ink cartridge to see if the safety strip has been removed from it.

replace another black cartridge the cartridge is factory defect

I have an HP Photsmart C4100 printer. I purchased remanufactured ink cartridges (both black and tri-colored) from Vivasmart. The black one works fine, but when I installed the tri-color, I got an error message that says "Print cartridge problem" The following print cartridge has a problem:
Tri-color. And I can't print. The screen on my printer says "Remove and check color cartridge." I have done this several times and it still won't print. I have turned off the power, removed the cartridges, and unplugged the unit, but it still didn't help. Any suggestions?

Take the printer back to where you got it from and exchane it for another one...

The black cartridge needs replacing it sounds like. On many printers, that is the only way that you get black.

I had this problem recently with my IP90. Both the black and color heads were clogged. After running the "canned" routines several times to clean the heads and deep clean the heads...still didn't help...here's what I did:

1. open the top lid to have the cartridges that are inserted in the print head move to the middle of the printer.
2. remove both cartridges
3. What is left there is the print head holder. Slightly move it to the right and gently lift the print head lock.
4. Grasp the print head and lift it out of the tank.
5. Have several paper towels hand and know that you will have color and bw ink on your fingers
6. Put the print head on the paper towel
7. Pour rubbing alcohol on the blk and color heads and let them sit of about 10-15 minutes.
8. after that dry the heads and re-insert them in the printer
9. I put new cartridges in the printer and ran clean and deep clean a few times.
10. My color and black and white print came right back!

Hope this helps.

have the printer preferences been changed accidentally to print in greyscale? Is the cartridge installed correctly? Now and again if the cartridges are opened and not installed straight away the ink dries up in the nossel and clogs the printer head, easily rectified with some cleaning solution. Cartridges also go out of date. hope this helped
